[QUOTE="kcebcj, post: 937605, member: 10391"] I think your thinking is right on. I'm no expert but I try to get 100% burn in the barrel finishing just before the bullet leaves the barrel. That generally is not an easy task but is achievable depending on powder choice. Quick Load gives an estimate and I have always gone by that. At the moment I'm working on a load for a 300 WM that is being built using IMR 7828 and 215gr Berger's. What I will probably work up to is 102% fill and 99.91% burn in a 27 inch barrel according to Quick Load and see what I have. If I bump the barrel to 28 inches it gets worse and the same if I drop back to a 26 inch....go figure. Things could change as I'm still knocking things around waiting for the barrel. I also usually get the best results when the powder burns 100% within the barrel but also the fill needs to be close to 100% or slightly compressed. Just my armature take on it. I see you are from the Central Coast...what part? I grew up in Arroyo Grande. [/QUOTE]
